More details on both SpaceX’s Merlin engine test yesterday as well as Orbital Sciences’ test firing of its Antares AJ-26 rocket engine on Monday.
SpaceX has successfully tested an upgraded version of its Merlin rocket engine. Video at the link.
Good news: Congressman Frank Wolf (R-Virginia) has backed down and modified the language he had inserted in the NASA budget bill that would have limited the number of commercial space companies NASA could subsidize.
From Clark Lindsey:
Rep. Frank Wolf (R-VA) , who is Chairman on the Commerce-Justice-Science subcommittee of the House Appropriations committee, put language into the recent House budget for NASA that requiree NASA to down-select immediately to one primary contractor in the commercial crew program. This would obviously eliminate competition on price and rule out redundancy in case one system is grounded. He has now relented and is willing to allow for “2.5 (two full and one partial) CCiCAP awards”.
As I wrote earlier, the success of Dragon is putting strong political pressure on Congress to support the independent commercial space companies over the NASA-built and very expensive Space Launch System (SLS) that Congress had mandated. Expect to see more elected officials back down in the coming year, with the eventually elimination of SLS from the budget.
We’ve only just begun: SpaceX has tentatively but quickly scheduled its first operational cargo flight to ISS for September 24.
The wrong side of history: Environmental activists have launched a petition drive to stop SpaceX from building a commercial spaceport near Brownsville, Texas.
“I love the space program as much, if not more, than anyone,” said Environment Texas Director Luke Metzger. “But launching big, loud, smelly rockets from the middle of a wildlife refuge will scare the heck out of every creature within miles and sprays noxious chemicals all over the place. It’s a terrible idea and SpaceX needs to find another place for their spaceport.”
This guy obviously doesn’t know that almost all of the Kennedy Space Center is a wildlife refuge, and a successful one at that. But then, what do facts have to do with most environmental causes?
Dragon has successfully fired its engines and released its trunk or service module. Splashdown is expected at 11:44 AM (Eastern).
Dragon has successfully undocked from ISS.
The hatch is closed and Dragon is ready for its return to Earth tomorrow morning.
From a past SpaceX critic: SpaceX’s Falcon Heavy could wipe out its launch competition.
This announcement [of SpaceX’s deal with Intelsat] is an indication that SpaceX is now threatening the dominance of Arianespace and ILS in the commercial launch arena. If a Falcon 9 Heavy can carry two or more large GEO communications satellites for half the launch price of an Ariane 5 or Proton M booking, then this could spell the end of their commercial operations as going concerns. It is not only on the commercial front that SpaceX may dominate. SpaceX’s Falcon 9 Heavy launch service promises to be less than half the cost of using equivalent Atlas and Delta rockets. So even the cosy launch provider-governmental relationships that previously benefited the likes of Boeing, Lockheed Martin and Pratt and Whitney/Rocketdyne could now be threatened.
As much of a fan of SpaceX as I am, and as much as I agree with the above statement, we must remember that Falcon Heavy is not yet built. Moreover, I suspect that the deal with Intelsat does not yet include any transfer of funds. SpaceX has a long way to go before any of this happens. Nonetheless, the company’s continued success very obviously is beginning to make its competitors nervous.
The competition heats up: SpaceX has gotten its first contract, with Intelsat, for its not-yet-built Falcon Heavy rocket.
The Falcon Heavy when completed will be the most powerful rocket since the Saturn 5. If SpaceX can get it funded through commercial contracts, it will end forever the need for government subsidies in the aerospace industry. Government as a customer will still exist, of course, but it will no longer be in charge.
The competition heats up: The privately-built Stratolaunch system has entered system design review.
The key quote from this article is this:
Scaled Composites, which is building the aircraft, has purchased two ex-United Boeing 747-400s, and is in the process of dismantling them. Stratolaunch will use the engines, hydraulics system and several other major components to build its own aircraft. The remaining fuselage and wing shells will be scrapped. SpaceX is building the rocket, which will launch approximately 13,000lb into orbit. “This is really going after the Delta II market,” says Steve Cook, Dynetics chief technologist. The group eventually hopes to qualify the system for human spaceflight and begin launched manned spacecraft. [emphasis mine]
Stratolaunch is not being built for NASA. It is aimed at the commercial market instead, with the intention of providing a cheaper alternative for getting large payloads into orbit.
The berthing of the privately-built Dragon capsule with the International Space Station on May 25 requires a bit of perspective to make clear the importance of this achievement.

Dragon’s dress rehearsal rendezvou last night was a success, and the spacecraft has been cleared to proceed with berthing tomorrow morning.
Dragon’s test rendezvous with ISS tonight has begun.
The rendezvous won’t be completed until 6:30 am (Eastern), with two orbital engine burns scheduled for 3 and 4 am. For further updates you can go here. Or you can watch everything on NASA TV.
Dragon has been approved to approach within 1.5 miles of ISS tonight in its first rendezvous test. More information here.
If this goes well tonight, Dragon will next attempt to approach the station close enough for its robot arm to grab it.
Several key elected officials who have generally been hostile to commercial space have commented positively to the successful launch of the Dragon capsule last night.
First, Senator Kay Bailey Hutchison (R-Texas) released this short statement:

Not surprisingly, last night’s successful launch of Falcon 9 has produced a large number of news articles. Rather than list them all, go to spacetoday.net for the links.
However, I think Clark Lindsey, in describing Elon Musk’s reaction to the successful launch, captured the most important aspect of last night’s success:

Falcon 9 has cleared the tower and is “looking good.”
First stage has completed its job and has been released. The second stage is firing as planned.
Dragon has separated from the second stage and is now in orbit. Now comes the real test of this mission: Can Dragon maneuver and rendezvous with ISS?
The best moment for the entire launch sequence was when Dragon’s solar arrays deployed. The camera link was still working, so that everyone could see it. When the arrays locked open, there was a gigantic roar from the crowd of people watching at SpaceX’s mission control. Dragon was in orbit and operational!
Tonight’s Falcon 9 launch: The countdown has begun, and the weather conditions have improved.
SpaceX will begin its own webcast at 3 am (Eastern), which is midnight here in Arizona.
An aside: The ashes of actor James Doohan, who played Scotty on the 1960s television show Star Trek, will be among 308 other cremated remains launched into space by Falcon 9 tonight. As one commenter for the above article noted quite appropriately,
You haven’t really covered any of the important questions here.
i.e. Are there enough dilithium crystals in the engine room to get Scotty up there? And are they using photon torpedoes to blast him out into space? And when they launch, will someone say, “Take her out, Mr. Sulu. Warp factor one.”?
Godspeed, Scotty old bean.
The Falcon 9 launch tonight is a go, with weather 80 percent favorable.
SpaceX is set to begin the countdown tonight for a 3:44 am (Eastern) May 22nd launch of Falcon 9/Dragon.
In an email update, SpaceX reports that they have found the cause of the Falcon 9 launch abort this morning.
During rigorous inspections of the engine, SpaceX engineers discovered a faulty check valve on the Merlin engine. We are now in the process of replacing the failed valve. Those repairs should be complete tonight. We will continue to review data on Sunday. If things look good, we will be ready to attempt to launch on Tuesday, May 22nd at 3:44 AM Eastern.
If this is true, than this entire exercise is an unqualified success and illustrates a certain robustness to SpaceX’s engineering on Falcon 9. Their control computer during the launch process spotted the problem before it caused a complete loss of the vehicle and payload. They can now locate the problem, fix it, and proceed with launch.
Last night Falcon 9’s computers shut the launch down at T minus zero seconds after sensing a high chamber pressure in one first stage engine.
Two thoughts, one good, one not so good.

Falcon 9 is now upright on launchpad for tomorrow morning’s 4:55 am (Eastern) launch. For continual updates, go here.
The Soyuz spacecraft with three astronauts has docked successfully with ISS.
Barring weather or another launch scrub, it looks like Saturday will be launch day for Falcon 9 and Dragon
An overview of what will happen on Dragon’s first flight to ISS next week.
The competition heats up: Bigelow and SpaceX announced today that they are teaming up to offer manned flights to space.
The SpaceX test launch of Dragon to ISS has now been rescheduled for May 19.
The test flight of Falcon 9/Dragon to ISS will almost certainly not launch on May 7.
It appears they need more time to assess the results of the static engine test on Monday.
SpaceX’s static fire test of the Falcon 9 still set for 3 pm today.
I will be discussing this story and the mining of asteroids on The Space Show today, even as this static fire occurs. Don’t forget to tune in.
Update: the static firing appears to have been a success, after an initial abort.
